Cofiring of biomass and coal at electrical generation facilities is gaining in importance as a means of reducing fossil fuel consumption, and more than 40 facilities in the United States have conducted test burns. Given the large size of many coal plants, cofiring at even low rates has the potential to utilize relatively large volumes of biomass. This could have important forest management implications if harvest residues or salvage timber are supplied to coal plants. Other feedstocks suitable for cofiring include wood products manufacturing residues, woody municipal wastes, agricultural residues, short-rotation intensive culture forests, or hazard fuel removals. Cofiring at low rates can often be done with minimal changes to plant handling and processing equipment, requiring little capital investment. Cofiring at higher rates can involve repowering entire burners to burn biomass in place of coal, or in some cases, repowering entire powerplants. Our research evaluates the current status of biomass cofiring in North America, identifying current trends and success stories, types of biomass used, coal plant sizes, and primary cofiring regions. We also identify potential barriers to cofiring. Results are presented for more than a dozen plants that are currently cofiring or have recently announced plans to cofire.

A systematic review that included 110 reports of eligible studies published from January 1985 through January 2011 was undertaken to determine the potential benefits and adverse effects of screening, monitoring, and treatments for adults with chronic kidney disease (CKD) stages 13. CKD stages 13 are defined as: 1 (kidney damage with a glomerular filtration rate (GFR) >90 mL/min/1.73 m2), 2 (kidney damage with a GFR of 6089 mL/min/1.73 m2), or 3 (a GFR of 3059 mL/min/1.73 m2, regardless of kidney damage). The systematic review excluded studies of patients with CKD stages 4 and 5. This is a summary of the systematic review meant to assist in decisionmaking along with a patients values and preferences and should not be construed to represent clinical recommendations or guidelines.

This paper describes the application of the optimization algorithm based on particle swarms known by its acronym as PSO, used to adjust the parameters of membership functions of a fuzzy logic controller (FLC) to find the optimal intelligent control for a wheeled autonomous mobile robot. Results of several simulations show that the PSO is able to optimize the type-1 and type 2 FLCs for this specific application.

While much advancement has been made in breast cancer treatment, metastatic breast cancer remains an incurable disease. MUC1 is a glycoprotein expressed on normal glandular epithelial but is over-expressed and underglycosylated in over 90of human breast tumors and 100of metastatic lesions, which lead to its ranking by NCI as the second most targetable antigen. Vaccines against tumor antigens have several benefits, including the chance to eliminate metastatic lesions that express the vaccinating tumor antigen. To this end, we have proposed vaccinating with peptides from the MUC1 protein core, which is only visible to the immune system on the tumor- associated form of the protein. Previous work from our lab has demonstrated that this vaccine does elicit a MUC1-specific immune response that can only be functional if the immunosuppressive tumor microenvironment is altered to allow efficient killing of tumor cells. Thus, we investigated the effectiveness of MUC1 vaccination in combination with drugs known to inhibit immunosuppression to determine which drug is the most effective. Methods: Mice that are transgenic for human MUC1 (MUC1.Tg) mice were orthotopically injected with a syngenic breast cancer cell line expressing human MUC1 (Mtag.MUC1). Mice were vaccinated after palpable tumor formation with the vaccine cocktail, consisting of two MHC class I-restricted MUC1 tandem repeat peptides and a class II pan helper peptide mixed with GM-CSF and CpG ODN, in incomplete Freund s adjuvant. Previous work in our lab has shown that blocking the cyclooxygenase pathway (COX) resulted in an inhibition of immunosuppression. Thus we used the following drugs in combination with the MUC1-vaccine therapy: Indomethacin (COX1 and COX2 inhibitor), Celecoxib (COX2 inhibitor), 1-methyl tryptophan (indoleamine 2,3 dioxygenase inihibitor), and AH6809 (EP2 receptor antagonist). Mice were euthanized and tissue was collected post the final vaccination.

The intelligent agriculture is one of the applications of Internet of Things (IOT),which has an extensive application and bright foreground.ZigBee Alliance formulated the ZigBee standards in the wireless sensor network tec hnology,that are recognized widely as authoritative standard of the Internet of Things,but ZigBee nodes,as the important unit of an intelligent monitoring system for agricultural environment,are the basic unit to reali ze the monitoring functi on.The paper briefly presents the architecture of ZigBee technology,designs the hardware architecture of ZigBee nodes on CC2531 (ZigBee coordinator and end node) and the software architecture of ZigBee nodes,and implements on botanical garden in QiongZhou University.The actual test result dermnstrates that the nodes can obtain the temperature,hum idity and illumination information in real tim e,and then transferred to the remote monitoring center.It has better actual application value.

No licensed vaccine is available in the United States. Because many human infections result in nonspecific or benign constitutional symptoms, establishing a diagnosis of Q fever often is challenging for clinicians. This report provides the first national recommendations issued by CDC for Q fever recognition, clinical and laboratory diagnosis, treatment, management, and reporting for health-care personnel and public health professionals. The guidelines address treatment of acute and chronic phases of Q fever illness in children, adults, and pregnant women, as well as management of occupational exposures. These recommendations will be reviewed approximately every 5 years and updated to include new published evidence.
